This is a fairly basic question but I did not find an answer to it anywhere

Suppose I have the following data frame (a and b are column names):

a      |       b
1      |    [x1,x2,x3,x4] # this is an array

Now I explode column b and logically get:

a      |       b
1      |      x1
1      |      x2
1      |      x3
1      |      x4

Are the values in the adjacent columns *actually* duplicated?
